Nutrient dynamics in a peatland forest riparian buffer zone and implications for the establishment of planted saplings
(2012)Forestry on peatland throughout the world is now focused on minimising destructive effects to the surrounding environment, especially during harvesting. These effects may be mitigated through the use of well-developed ... -
Nutrient dynamics in a peatland forest riparian buffer zone and implications for the establishment of planted saplings.
(2012)Forestry on peatland throughout the world is now focused on minimising destructive effects to the surrounding environment, especially during harvesting. These effects may be mitigated through the use of well-developed ... -
Nutrient, metal and microbial loss in surface runoff following treated sludge and dairy cattle slurry application to an Irish grassland soil
(Elsevier, 2015)Treated municipal sewage sludge ( biosolids ) and dairy cattle slurry (DCS) may be applied to agricultural land as an organic fertiliser. This study investigates losses of nutrients in runoff water (nitrogen (N) and ... -
On-farm treatment of dairy soiled water using aerobic woodchip filters
(Elsevier, 2011)Dairy soiled water (DSW) is produced on dairy farms through the washing-down of milking parlours and holding areas, and is generally applied to land. However, there is a risk of nutrient loss to surface and ground waters ... -
Operational coefficient of consolidation around a pile group driven in clay/silt
(Springer-Verlag, 2013)Although finite element packages facilitating coupled consolidation analyses are increasingly in use, many practitioners still favour linear uncoupled analysis out of familiarity with the use of coefficients of consolidation. ... -
Operational fatigue loading on tidal turbine blades using computational fluid dynamics
(Elsevier, 2020-01-20)As the world moves to a greater reliance on renewable energy, a vital component will be the predictability and dependability of the energy source; tidal energy provides such a solution. Horizontal axis tidal turbines are ... -
Optimizing nitrate removal and evaluating pollution swapping trade-offs from laboratory denitrification bioreactors
(Elsevier, 2014-10-29)Denitrification bioreactors, typically containing woodchips, are artificial sinks used to remediate nitrate (NO3-) losses on agricultural landscapes. Analysis of these bioreactors frequently considers their efficacy in ... -
Packaging environmental impact on seafood supply chains: A review of life cycle assessment studies
(Wiley, 2021-08-24)Packaging is fundamental for food preservation and transportation but generates an environmental burden from its production and end-of-life management. This review evaluates packaging contribution to the environmental ... -
Partnering for success: a students’ union-academic collaborative approach to supplemental instruction
(Taylor & Francis (Routledge), 2021-03-16)This paper examines the successes and challenges of a Supplemental Instruction/Peer Assisted Learning (SI/PAL) scheme at an Irish Higher Education Institute that was the outcome of a co-working approach between academic ... -
Performance and surface clogging in intermittently loaded and slow sand filters containing novel media
(Elsevier ScienceDirect, 2016-05-20)Slow sand filers are commonly used in water purification processes. However, with the emergence of new contaminants and concern over removing precursors to disinfection by-products, as well as traditional contaminants, ... -
Performance of a stratified sand filter in removal of chemical oxygen demand, total suspended solids and ammonia nitrogen from high-strength wastewaters.
(Journal of Environmental Management, 2007-06-01)A stratified sand filter column, operated in recirculation mode and treating synthetic effluent resembling high strength dairy wastewaters was studied over a 342 day duration. The aim of this paper was to examine the ... -
The performance of constructed wetlands treating primary, secondary and dairy soiled water in Ireland (a review).
(Journal of Environmental Management, 2011-11-01)In Ireland, no database detailing the design, influent loading rates or performance of constructed wetlands (CWs) exists. On account of this, they are designed without any protocol based on empirical data. The aim of ... -
The performance of granitic, shale and limestone forest road aggregates under repeated loading
(American Society of Civil Engineers, 2014-01-20)This study compared the performance of three aggregate layerings, commonly used in the construction of unbound forest roads in Ireland, when they were subjected to repeated loading in a new large-scale test rig. These ... -
Performance of novel media in stratified filters to remove organic carbon from lake water
(IWA Publishing, 2016-08-15)Disinfection by-products (DBPs) are an ever-increasing occurrence in water networks, particularly those which abstract water from peatland areas. Although much research has been carried out to discover novel methods to ... -
Permeable reactive interceptors: blocking diffuse nutrient and greenhouse gases losses in key areas of the farming landscape
(2014)Engineered remediation technologies such as denitrifying bioreactors target single contaminants along a nutrient transfer continuum. However, mixed contaminant discharges to a water body are more common from agricultural ... -
Phosphorus and nitrogen leaching from an organic and a mineral soil receiving single and split dairy slurry applications: A laboratory column experiment
(Springer, 2022-11-12)Purpose Intensification of farming means that organic soils, of low phosphorus (P) holding capacity, are being brought into production. Consequently, farmers may have to adjust their fertiliser application regimes to ... -
Phosphorus fertiliser equivalent value of dairy processing sludge-derived STRUBIAS products using ryegrass (Lolium perenne L.) and spring wheat (Triticum aestivum)
(Wiley, 2023-12-11)Struvite, biochar and ash products (collectively known as STRUBIAS) products derived from different waste streams are used as fertilisers in agriculture. Raw dairy processing sludge (DPS) shows promise as bio-based ... -
Pile group settlement estimation: suitability of nonlinear interaction factors
(American Society of Civil Engineers, 2015-06)In this paper, predictions of pile settlement determined by appropriate superposition of two-pile interaction factors are compared with those computed from continuum analysis. A finite-element package is used in conjunction ... -
Pile groups under axial loading: an appraisal of simplified non-linear prediction models
(Thomas Telford (ICE Publishing), 2019-06-12)The settlement behaviour of vertically loaded pile groups has been the subject of an extensive body of research over the past two decades. In particular, this work has identified the over-conservatism associated with ... -
A Pleistocene deposit preserved in deep karst at Coolough, County Galway, western Ireland
(John Wiley and Sons, 2020-11-05)Buried karst features result from a complex interplay between carbonate bedrock and structural geology. The enhancement of carbonate aquifers through this interplay creates hydrogeologically complex subsurface drainage ...
